This post demonstrates the effects of running a Double Tagging VLAN Hopping attack against the ProxMox hypervisor environment. In this scenario there are two Cisco 2950 switches in between the attacker and the virtual network. The experiment was performed on seven different hypervisor/virtual network configurations in order to perform a systematic evaluation of the effects across all of the major enterprise level virtualization platforms. The following network diagram illustrates the configuration used for each of the experiments:

This post includes a demo video which illustrates the effects of a Switch Spoofing attack launched from within a virtualized networking environment. The experiment was performed on seven different hypervisor/virtual network configurations in order to perform a systematic evaluation of the effects across all of the major enterprise level virtualization platforms. The following network diagram illustrates the configuration used for each of the experiments:

I have had to create a few CentOS 7 minimal router systems over the past few weeks for my research environments and decided to document the process. CentOS 7 makes use of systemd and firewalld which is a change from previous versions which were openrc and iptables based. The process of creating a minimal router system is fairly straight forward and can be completed in a very short amount of time after the initial installation with minimal dependencies.
